Spiritualists and Mediums. I don't know, what I do know is that there is no scientific proof of their ability to contact "The other side". I have seen stage "magicians" doing the same thing and admitting that it was a trick, but this does not prove that the others are tricksters.

Are they genuine? Any proof? Even if they are fakes does it matter if others get a peace of mind from listening to them? Do they cause harm?

And who are those people wearing 18th century dresses?I met some in Belize,but did not find it appropriate to ask them questions.
